Well the probabilities of one or more different outcomes have to add up to 100%. You can't have one outcome be 90% and another be 20% because it does not equal 100%.
So if you know the percentage of one outcome you have to subtract that from 100%
That means C is your answer.
Answer:
The rate at which the account pay the deposit is 2 %
Step-by-step explanation:
Given as :
The principal amount deposited in account = $2100
The rate of interest = r % simple interest annually
The time period = 11 months = 
year
The amount received = $2138.50
Now<u>, From Simple Interest method </u>
Simple Interest = 
Or, Interest = 
Or, Interest = 
Or, Interest = 19.25 r
Now, Interest = Amount - Principal
So, 19.25 r = $2138.50 - $2100
Or, 19.25 r = $38.5
∴ r = 
I.e r = 2
So, rate of interest = r = 2 %
Hence The rate at which the account pay the deposit is 2 % Answer
Answer:
x = -3
y = 9
Step-by-step explanation:
Add two equations up
4x + 5y - 9x - 5y = 33 - 18 add or subtract like terms
-5x = 15 divide both sides by -5
x = -3 we can use this information to find the value of y
4x + 5y = 33 replace x with -3
4 * (-3) + 5y = 33
-12 + 5y = 33 add 12 to both sides
5y = 45 divide both sides by 5
y = 9

Answer:
2/9
Step-by-step explanation:
To determine the fraction of students that walk to school, take the fraction of students that do not ride the bus and multiply by the fraction that walk
6/15* 5/9
Simplify the fractions
6/15 Divide the top and bottom by 3
2/5
2/5 * 5/9 = 2/9
